Focusing the Autofocus:
The a Autofocus group in the first level of the Custom Settings menu contains a variety of advanced autofocus options. This chapter details options that can be used to frame moving subjects at sporting events: a1 (AF-Cpriority selection), a3 (Dynamic AF area), and a4 (Focus tracking with lock-on). These options are best used with the focus mode selector rotated to C (continuous-servo AF) and the AF-area mode selector rotated to I (dynamic-area AF).

There are many Sun Microsystems technologies that use Ajax [Ajax], and more than one way to use Ajax on mobile platforms. For example, applications written using the Java Platform, Enterprise Edition (Java EE, formerly known as J2EE) may generate XML, JSON [JSON], XHTML and/or ECMAScript destined for mobile browsers.

The rise of the software-as-a-service paradigm has led to the development of a new breed of sophisticated, interactive applications often called Web 2.0. While web applications have become larger and more complex, web application developers today have little visibility into the end-to-end behavior of their systems.

Many developers will have read Herb Sutter’s article “The Free Lunch is Over” which talks about the future speed increases of CPUs. The good news is that they will get significantly faster, but the bad news is that you won’t see all of the possible performance gains unless you write your application to take advantage of them. Over the last few years the increase in clock speeds has slowed down, and chip manufacturers are focussing more and more on concurrent execution of code. Hyperthreading was the first step, which allows a single processor core to execute two threads in parallel, but the future is multi-core chips which will allow many threads to execute truly independently. Intel is already talking about chips with over a hundred cores, so if your code is single-threaded you may only be using one hundredth of the available processing power!

We’ll briefly demonstrate a very simple example of Photoshop’s ability to create interesting images entirely from scratch, rather than merely editing existing image material. We’ll be creating a colorized lightning bolt. First, create a new image. Make it 800 x 600 pixels in size, at 72 pixels/inch (recall this is the resolution of a monitor), and make the background contents transparent. Make sure the color mode is RGB.

Modern object-oriented programming languages like Java or C# support multithreaded programming. They allow several threads to run concurrently sharing objects on the heap in the same address space. Each thread has its own frame stack, program counter, local variables and registers. The languages have special syntactical constructs for synchronization. Java has a synchronized statement and synchronized methods, while C# has a lock statement and several attributes that can be applied to classes and methods to control their run-time synchronization behavior.

C# is a modern object-oriented language for application development. In addition to object-oriented constructs, C# supports component-oriented programming with properties, methods and events.

UML defines graphical notations for describing and designing object-oriented software systems. It’s an open standard controlled by the Object Management Group (OMG). Although UML has many diagram types, we’ll focus on class models that show static class structure and relationships.
